Model building for tilted transversely isotropic media has commonly been performed by a single parameter tomography that updates the velocity in the symmetry direction, while the orientation of the symmetry axis and Thomsen parameters [Formula: see t

We propose a method of tomography that utilizes the time residual and other attributes associated with each wavelet in beam migration. This time residual is referred to as 3D residual normal moveout (3DRNMO) and is related to error in the velocity mo

Summary Whil e multi-azimuth surveys offer much more information than conventional narrow azimuth surveys, it is a challenge to effectively and efficiently utilize all azimuths to build a reliable velocity model. We propose the following strategy: mi

Multi-azimuth acquisition has been shown to be beneficial for attenuating multiple diffraction energy and improving illumination. In this case study on a multi-azimuth dataset from the Nile Delta we demonstrate that multi-azimuth reflection tomograph

Automatically picking on 3D volumes and fast convergence to variable wavelength are two major challenges in grid-based reflection tomography. This paper discusses a multi-parameter controlled automatically picking method that, when integrated with a

Tomography has been widely employed for velocity model building. The typical work flow starts with the migration of an initial velocity model. This is followed by picking residual moveouts and then updating the velocity through tomography. The migrat

Summary We present a general algorithm to perform tomographic velocity updating in 3D inhomogeneous VTI media. The residuals for this tomographic update are based on a polynomial curve generated using an automated residual moveout program. We apply a

We have developed a method to reduce the P-S converted wave (c-wave) acquisition footprint caused by irregular geometry effects during acquisition. This method incorporates a weighting scheme based on the relative area in a time slice that is associa

Summary Properly controlled migration amplitudes are essential in amplitude versus offset analysis. Usually this is achieved by incorporating the amplitude weight factors in the Kirchhoff summation. This involves building tables of in-plane and out-o
